COP21 is the biggest climate conference in years. But some think that it’s more than tainted by its corporate sponsorship. “By sponsoring the climate talks, major polluters such as Air France and GDF-Suez-Engie can promote themselves as part of the solution – when actually they are part of the problem,” Joe Elan of Brandalim wrote in a press release statement. “We are taking their spaces back because we want to challenge the role advertising plays in promoting unsustainable consumerism. Because the advertising industry force feeds our desires for products created from fossil fuels, they are intimately connected to causing climate change.”

Project Brandalism “reclaimed” 600 advertisement spaces in Paris with art that denounced consumerism and corporate greenwashing. COP21 is set in an airport and 20% of its financing comes from car manufacturers, airlines, and banks.
